[0030] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described in detail with reference to the accompanying drawings. Unless otherwise explicitly specified and limited, terms such as "installation," "connection," "linking," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. When one component is referred to as being "on" or "below" another component, the component can be located "directly" or "indirectly" on the other component, or there may be one or more intermediary components. The terms "first," "second," etc., are used only for the convenience of describing this technical solution and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. Fluid communication between two spatial structures means that fluids such as gases and liquids can flow between them. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0031] Please see Figures 1 to 3 This utility model discloses an embodiment of an aerosol generating device, which includes a housing 1, a support, a base 3, and a heating element 4. The housing 1 forms a receiving cavity, and the support, base 3, and heating element 4 are disposed within the receiving cavity. The support defines a receiving area 20 (see...). Figures 8 to 10 The base 3 and the heating element 4 are disposed within the receiving area 20. The heating element 4 forms a heating cavity for accommodating the aerosol generating matrix 6. That is, the aerosol generating matrix 6 can be inserted into the heating cavity, and the heating element 4 thereby surrounds the aerosol generating matrix 6 and heats it circumferentially. When energized, the heating element 4 generates heat to heat and atomize the aerosol generating matrix 6 located in the heating cavity to generate aerosol. Specifically, the heating element 4 includes a heating substrate and a heating element disposed on the heating substrate. In some embodiments, the heating substrate is a tubular structure open at both ends, and the hollow portion of the heating substrate forms the heating cavity. The heating substrate can be a metal tube open at both ends. The heating element can be a heating film disposed on the surface of the heating substrate. The aerosol generating device also includes a power supply unit, which includes components such as a battery. The heating film and the power supply unit are mechanically and / or electrically connected. When the heating film is energized, it generates heat to heat and atomize the aerosol generating matrix 6 located in the heating cavity to generate aerosol.

[0032] Aerosols can be visible or invisible and may include vapors (e.g., fine particulate matter in a gaseous state, which are typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. The aerosol-generating matrix 6 is a processed article that, when heated, can generate aerosols. The aerosol-generating matrix 6 can be in a liquid, fully solid, or semi-solid state. The aerosol-generating matrix 6 includes, but is not limited to, plant materials, fragrance materials, smoke-generating substances, adhesives, etc. Figures 1 to 5 As shown, in some embodiments, the outer casing 1 is generally a longitudinally elongated hollow column, comprising a second sidewall 11 and a top cover 12 that are joined together. The second sidewall 11 and the top cover 12 can be rotatably connected, that is, one end of the top cover 12 and the second sidewall 11 is connected by a rotating assembly. Thus, the top cover 12 can be flipped relative to the second sidewall 11. The top cover 12 has an exhaust channel 120, which communicates with the heating chamber and the external atmospheric fluid, for discharging aerosols. The exhaust channel 120 can be an exhaust channel of a certain length or a single exhaust port.

[0033] In some embodiments, the aerosol generating device may further include a filter 5, which is installed at the air outlet channel 120 of the top cover 12 and has an air outlet hole 50 that communicates with the heating chamber and the external atmospheric fluid. The filter 5 is used to filter the aerosol generated in the heating chamber and to export the filtered aerosol for the user to inhale. Alternatively, in other embodiments, the filter 5 may be omitted, and the aerosol generating article may be inserted into the heating chamber. The aerosol generating article has an aerosol generating matrix 6 and a filter section. The heating chamber is located just outside the aerosol generating matrix 6, and the end of the filter section away from the aerosol generating matrix 6 extends out of the receiving chamber. The aerosol is filtered and exported for the user to inhale through the filter section of the aerosol generating article.

[0034] The aerosol generating device also includes an air intake channel that connects the outside atmosphere to the heating chamber. Under the suction force provided by the user, outside air can enter the heating chamber through the air intake channel, carrying the aerosol out for the user to draw in.

[0035] like Figure 1As shown, in some embodiments, the air intake channel includes an air inlet 13 disposed on the second sidewall 11. The air inlet 13 extends through the inner and outer sides of the second sidewall 11 along its thickness direction. The air inlet 13 is in fluid communication with the outside atmosphere. In some embodiments, the air inlet 13 may be disposed at the junction of the second sidewall 11 and the top cover 12. Specifically, the surface of the top cover 12 facing the second sidewall 11 (the lower end face of the top cover 12) is partially recessed to form a first notch; the surface of the second sidewall 11 facing the top cover 12 (the upper end face of the second sidewall 11) is partially recessed to form a second notch. The opening directions of the first notch and the second notch are opposite to each other; that is, the first notch faces downwards, and the second notch faces upwards. Therefore, it is only necessary to reserve the first notch when the top cover 12 is formed, and the first notch can be formed during the forming process of the top cover 12; it is only necessary to reserve the second notch when the second side wall 11 is formed, and the second notch can be formed during the forming process of the second side wall 11, eliminating the need for separate drilling at other locations on the second side wall 11 or the top cover 12, making the manufacturing process simpler.

[0036] like Figure 3 , Figure 8 and Figure 9 As shown, in some embodiments, the air intake passage further includes at least one first air intake passage 24. The bracket includes a first sidewall 21 and at least one patch 7. (As...) Figures 4 to 9 As shown, the first sidewall 21 has an outer wall surface 211 and an inner wall surface 212, wherein the outer wall surface 211 faces the second sidewall 11 of the outer casing 1, and the inner wall surface 212 faces the heating element 4. The outer wall surface 211 of the first sidewall 21 is partially recessed to form at least one groove 25. A patch 7 covers the outside of the groove 25 (i.e., the opening side of the groove 25 facing the second sidewall 11 of the outer casing 1). A first air intake channel 24 is defined between the bottom surface of the groove 25 and the patch 7. The bottom surface of the groove 25 refers to the surface of the groove 25 furthest from the outer wall surface 211 of the first sidewall 21. The first air intake channel 24 is in fluid communication with the air inlet 13 and the heating chamber, respectively, to introduce outside air into the heating chamber. That is, the first air intake channel 24 connects the outside atmosphere and the heating chamber in fluid communication through the air inlet 13. Air flows through the aerosol generation matrix 6 in the heating chamber to carry out the aerosol for the user to inhale. The first air intake channel 24 preheats the air entering the heating chamber, thereby improving atomization efficiency.

[0037] In summary, the heating chamber is connected to the external atmospheric fluid through the air intake channel to realize the air intake function; the first air intake channel 24 is defined by the bottom surface of the groove 25 on the first side wall 21 and the patch 7. The first air intake channel 24 is formed inside the structure of the bracket. The air intake structure is relatively simple and can release the space below the heating component 4, which is conducive to the miniaturization of the aerosol generating device.

[0038] like Figure 4 and Figure 5 As shown, in some embodiments, the area of ​​the patch 7 is smaller than the area of ​​the groove 25. The patch 7 covers a portion of the groove 25, and the remaining portion of the groove 25 not covered by the patch 7 is in fluid communication with the air inlet 13. Specifically, a reserved area at the upper right corner of the groove 25 is not covered by the patch 7, and this reserved area is directly opposite and connected to the air inlet 13. All the outside air entering from the air inlet 13 enters the first air intake channel 24 through the portion of the groove 25 not covered by the patch 7.

[0039] like Figure 6 and Figure 9 As shown, in some embodiments, the groove 25 may include a first recessed area 251 and a second recessed area 252. The second recessed area 252 is located around the first recessed area 251. The recess depth H1 of the first recessed area 251 relative to the outer wall surface 211 is greater than the recess depth H2 of the second recessed area 252 relative to the outer wall surface 211, and the patch 7 is embedded in the second recessed area 252. The groove bottom surface of the first recessed area 251 and the patch 7 define a first air intake channel 24. The groove bottom surface of the first recessed area 251 refers to the surface of the first recessed area 251 that is furthest from the outer wall surface 211 of the first sidewall 21. Specifically, the patch 7 and the groove bottom surface of the second recessed area 252 are fitted together. The outer contour shape and size of the groove bottom surface of the second recessed area 252 are adapted to the outer contour shape and size of the patch 7.

[0040] like Figure 6 As shown, in some embodiments, the width W of the groove bottom surface of the second recessed area 252 is greater than or equal to 1.1 mm to ensure that the groove bottom surface of the second recessed area 252 has sufficient adhesive area for the patch 7 to be attached thereto. The material of the patch 7 may include at least one of polycarbonate (PC), polyethylene terephthalate (PET), metal, and plastic.

[0041] like Figure 7 and Figure 10 As shown, in some embodiments, the bracket further includes a top wall 23 and a bottom wall 22, and the first side wall 21 is connected to the top wall 23 and the bottom wall 22 at opposite ends along the vertical direction, respectively; that is, the first side wall 21 is connected between the top wall 23 and the bottom wall 22. The top wall 23 is in contact with the top cover 12.

[0042] like Figure 3As shown, in some embodiments, a heat insulation layer 8 is provided between the inner wall surface 212 and the heating element 4. The heat insulation layer 8 is used to isolate the heat between the first side wall 21 of the bracket and the heating element 4, so as to prevent the cold air in the first air intake channel 24 from contacting and carrying away the heat of the heating element 4, thereby avoiding affecting the heating effect of the aerosol generation matrix 6 and avoiding increasing energy consumption. Further, the heat insulation layer 8 may include aerogel or other materials with heat insulation properties. Aerogel is a porous material with nanoscale pores and extremely high porosity, containing a large amount of air. The nanoporous structure of aerogel makes the material have extremely low thermal conductivity and good heat insulation effect. Therefore, using aerogel as the heat insulation layer 8 can further improve the heat insulation effect and reduce energy consumption. The base 3 and the inner wall surface 212 are sealed together, thereby sealing the gap between the base 3 and the first side wall 21, effectively preventing the air flowing through the air intake channel from contacting the heat insulation layer 8, and ensuring the airtightness of the air intake channel.

[0043] like Figure 3 and Figure 7 As shown, in some embodiments, the aerosol generating device further includes an annular seal 90, which is clamped between the base 3 and the inner wall surface 212 of the first sidewall 21. The seal 90 can be an elastic element, for example, made of silicone, rubber, or similar materials. The base 3 and the inner wall surface 212 are tightly fitted with the seal 90, thereby sealing the gap between the base 3 and the inner wall surface 212. Therefore, the base 3 and the inner wall surface 212 can be sealed together by the seal 90.

[0044] like Figure 10 As shown, in some embodiments, the aerosol generating device further includes a circuit board 9, which is disposed on the outer side of the first sidewall 21. Since the first air inlet channel 24 is formed inside the first sidewall 21, and the circuit board 9 is disposed on the outer side of the first sidewall 21, the air entering the aerosol generating device will not flow through the circuit board 9, thus avoiding the problem of odor generation caused by airflow passing through the circuit board 9. Specifically, the circuit board 9 is disposed on the opposite side of the patch 7, and the circuit board 9 can be fixed to the inner wall surface 212 or the outer wall surface 211 of the first sidewall 21 by fasteners.

[0045] like Figure 3 , Figure 6 and Figure 11As shown, in some embodiments, the air intake channel further includes a second air intake channel 30 formed on the base 3, and the heating component 4 abuts against the base 3. The second air intake channel 30 is in fluid communication with the first air intake channel 24 and the heating chamber, respectively. That is, the first air intake channel 24 is in fluid communication with the heating chamber through the second air intake channel 30. Thus, the air inlet 13, the first air intake channel 24, the second air intake channel 30 and the heating chamber are in sequential fluid communication. External air flows through the air inlet 13, passes through the first air intake channel 24 and the second air intake channel 30, and then enters the heating chamber. The aerosol generated by the aerosol generating matrix 6 in the heating chamber is heated and atomized, and the resulting aerosol mixes with the air and is then discharged through the air outlet channel 120 for the user to inhale.

[0046] like Figure 3 As shown, in some embodiments, the heating element 4 is a tube extending through both ends, and the heating element 4 and the base 3 are nested together. For example, the heating element 4 may be sleeved around the base 3, or the base 3 may be sleeved around the heating element 4.

[0047] like Figure 11 As shown, in some embodiments, the base 3 includes a tube 31 and a seat 32 connected to each other. The tube 31 is tubular with both ends open, and a cavity is formed in the tube 31. The tube 31 can be a hollow cylinder, a hollow square prism, or other shapes. That is, the cross-sectional profile of the tube 31 can be a regular or irregular shape such as a circle, rectangle, triangle, or polygon. The tube 31 and the heating element 4 are coaxially arranged, and the cavity and the heating cavity are in fluid communication. Figure 3 As shown, in some embodiments, a sealing section 61 is connected below the aerosol generating matrix 6, and the sealing section 61 and / or the aerosol generating matrix 6 can be contained within the cavity. The second air inlet channel 30 includes the cavity and a plurality of first air inlets 301 spaced circumferentially along the pipe body 31, each first air inlet 301 penetrating the pipe wall of the pipe body 31. The number of first air inlets 301 can be two, three, four, five, etc. Each first air inlet 301 is in fluid communication with the cavity and the first air inlet channel 24, respectively. Air flowing from the first air inlet channel 24 to the second air inlet channel 30 is first diverted through the first air inlet 301 and then enters the cavity and the heating chamber sequentially. Since the first air inlet 301 is distributed circumferentially along the pipe body 31, the air from the first air inlet channel 24 enters the pipe cavity in different directions around the pipe body 31 and then merges into the heating chamber. As a result, the airflow entering the heating chamber is more uniform, avoiding the loss of kinetic energy caused by chaotic airflow, thereby improving the efficiency of aerosol carry-out.

[0048] Furthermore, to improve the uniformity of the intake airflow, in some embodiments, the spacing between each first intake hole 301 along the circumference of the pipe body 31 is equal, that is, the spacing between any two adjacent first intake holes 301 along the circumference of the pipe body 31 is equal. The maximum width of each first intake hole 301 can be greater than 1 mm. Specifically, each first intake hole 301 can be a regular or irregular shape such as a circle, rectangle, triangle, or polygon. When the first intake hole 301 is a circular hole, the maximum width of the first intake hole 301 refers to its diameter, that is, the diameter of the first intake hole 301 is greater than 1 mm; when the first intake hole 301 is a rectangular hole, the maximum width of the first intake hole 301 can refer to its maximum side length, that is, the maximum side length of the first intake hole 301 is greater than 1 mm; when the first intake hole 301 is a square hole, the maximum width of the first intake hole 301 refers to any side length, that is, any side length of the first intake hole 301 is greater than 1 mm. Furthermore, the maximum width of each first air inlet 301 can be greater than 1.2 mm, so that the airflow velocity through the first air inlet 301 is not too high, and there is sufficient air intake to meet the requirements of large flow rate suction.

[0049] like Figure 11 As shown, in some embodiments, the base 32 is disposed around the tube 31, and the cross-sectional dimension of the base 32 is larger than that of the tube 31. The base 32 and the tube 31 can be integrally formed or separate structures. The second air intake channel 30 also includes a second air intake hole 302 formed on the base 32. Specifically, the second air intake hole 302 is directly opposite the first air intake hole 301. The second air intake hole 302 is in fluid communication with the first air intake hole 301 and the first air intake channel 24, respectively. That is, the first air intake hole 301 and the first air intake channel 24 are in fluid communication through the second air intake hole 302. Thus, the air inlet 13, the first air intake channel 24, the second air intake hole 302, the first air intake hole 301, the tube cavity, and the heating cavity are in sequential fluid communication. The air from the first air intake channel 24 first passes through the second air intake hole 302 and then enters the first air intake hole 301, forming a two-stage air intake. The second air intake hole 302 plays a role in balancing the airflow.

[0050] like Figure 11 As shown, in some embodiments, the seat 32 has a first surface 321 facing away from the tube body and a second surface facing the tube body. A second air inlet penetrates the first surface 321 and the second surface. Combined with... Figure 3As shown, the seal 90 is sandwiched between the first surface 321 and the inner wall surface 212. Thus, the first surface 321 and the inner wall surface 212 are tightly fitted with the seal 90, thereby sealing the gap between the first surface 321 and the inner wall surface 212. Furthermore, the minimum distance between the first air inlet 301 and the first surface 321 can be greater than or equal to 1 mm to obtain a more uniform airflow. The minimum distance between the first air inlet 301 and the first surface 321 refers to the minimum distance between the first air inlet 301 closest to the first surface 321 and the first surface 321, that is, the vertical distance between the outer contour line of the first air inlet 301 closest to the first surface 321 and the first surface 321.

[0051] In some embodiments, the total area of ​​the second air inlet 302 is larger than the total area of ​​the first air inlet 301. For example... Figure 11 In the illustrated embodiment, there is one second air inlet 302, and the area of ​​this second air inlet 302 is greater than the sum of the areas of all the first air inlets 301. Alternatively, in some other embodiments, there may be more than one second air inlet 302. Because the total area of ​​the second air inlets 302 is greater than the total area of ​​the first air inlets 301, it can be ensured that the airflow through the second air inlets 302 is greater than the airflow through the first air inlets 301, ensuring that a sufficient amount of airflow reaches the first air inlets 301 through the second air inlets 302 and is diverted, thus preventing the problem of multi-stage air intake interception.

[0052] like Figure 6 As shown, in some embodiments, the groove 25 includes a first portion that does not penetrate the inner wall surface 212 and a second portion 253 that penetrates the inner wall surface 212, the second portion 253 being in fluid communication with the second air intake channel 30. For ease of understanding, the entire area of ​​the groove 25 except for the second portion 253 can be set as the first portion that does not penetrate the inner wall surface 212. All air flowing through the first air intake channel 24 is concentrated and output to the second air intake channel 30 by the second portion 253. Further, the area of ​​the second portion 253 and the area of ​​the second air intake hole 302 can be equal. Even further, the area of ​​the second portion 253, the area of ​​the annular region formed by the seal 90, and the area of ​​the second air intake hole 302 can all be equal.

[0053] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
